Application flied 27, 1921 T-Eq ms 7 m, m 411, lb nilcWIi snat- I .u FAQ u in lLL limo/Brim, e. citizen oi the United rat-lites,

residing at Denver, in the county of Denver and State of Colorado, have invented certain new and. useful improvements in Vehicle Rims, of which the following is a specificetion.

My invention relates to rims for pneumatic tires, and has for its object to provide a rim for vehicles on which pneumatic tires are used, which rim may he quickly and easily removed from the pneumatic tire without the use of tire tools;

These objects 1 accomplish with the rim illustrated in the accompanying drawings, in which similar letters and numerals of reference indicate like parts throughout the several views, and as described in the speciilcation forming a pert of this application and pointed out in the appended claims;

In the drawings in which i have shown 11 substantial embodiment of my invention, Figure 1 is e. side elevation of a portion of an out. )bllE wheel showing my invention in piece thereon. Figure 2 is a portion of the rim with the tire and wheel removed,- and showing the device fully operated to collapse the rim. Figure 3 is a portion of the rim with the device only partially oper ated. Figure 4 is an elevation showing a portion of the rim with my device in piece thereon at the joint.

In removing from and replacing deflated pneumatic tires on vehicle wheel rims of the demonntsble rim type some use the common tools about the vehicle, others provide .tire tools of special and intricate construction and operation to remove the tire. I provide an improved riin heving special members attached thereon which are easily operated, simple and etlicient', and "bywhirh the rim is lessened in circumfereni're end the tire changed ready for iniiation in less time than now practiced. In the present invention the common channel metal rim form A is usedhaving outwardly extended flanges thereon,

and where the joint is made the ends of the flat lugs i2 and 5 positioned on opposite sides and st or near the jointin seid rim. They T 1 "int '3 t son us. 1.1%,

and are spaced to not interfere with the common holding lugs B. A lever 1 is hingedly connected at one end by the pivot 4 with said lug-s3, and fulcrumed on the other two of said lugs 2 by the pivot pin 5. A longitudinally disposed channel recess 7 is left between said lugs 2 and 3 to receive the said lever 1 when said lever has been thrown into the locked position, as shown in Figures 1 and i.

The operation of my device is as follows: Desiring to remove a tire the operator moves the lever 1 toward the axis of the rim A, which movement draws the ends 'of the rim to the position shown in Figure 3 and completing the saio movement collapses the rim and throws the device to the position shown in Figure 2, The circumference of the rim is thus reduced endthe tire may be easily removed and the other the laced around the rim. The movement of the lever 1 in the reverse direction will extend the rim and fasten it within the tire by the spring tension of the rim, which rim is uncut except at the joint. It will he noticed in Figure 4 that the lugs 2-2 and 3-3 integral with the rim extend for considerable distances on either side of the split, and the lever l fits snugly in the channel between the lugs. By thus extending the lugs along the sides of the rim and rushing them integral therewith and having the lever fitting "snugly from one end to the other of the extended lugs on both sides of the rim, 1 have iound by ex perience that this construction secures a maximum strength of these parts to resist any sidewise thrust of either end of the rim, end this being the weakest point in a split rim, my construction offers the maximum strength just where it is needed.

I thus provide 11 new and novel vehicle rim with link connections at the joint made by the lever 1, e'portion of which lever is ofe'sid rim adjacent the split therein, one peir oi lugs proje'ctinglbeyond one end of the rim to which they are ettached, and

the character described, a

' tending elong parallel with the side of the 1.im,-t other pair of lugs extending to within a short distance of the other end of the rim to. abut the ends of the other pair of the other peg r .of said lugs, and lying snugly in the, channel between both pair of 10.

lugs when the rim is extended, the construetion being such as to offer the maximum resistance to a sidewise strain on the ends of therim.

In testimony whereof, I have e'fiixed my 15 signature.
